RESUMO

Skin ageing is a phenomenon resulting from the aggregative changes to skin structure and function and is clinically manifested by physical features such as wrinkles, hyperpigmentation, elastosis, telangiectasia, and deterioration of skin barrier integrity. One of the main drivers of skin ageing, UV radiation, negatively influences the homeostasis of cells and tissues comprising the skin by triggering production of immune-mediated reactive oxygen species (ROS) and pro-inflammatory cytokines, as well as a various hormones and neuropeptides. Interestingly, an established link between the gut and the skin coined the 'gut-skin axis' has been demonstrated, with dysbiosis and gut barrier dysfunction frequently observed in certain inflammatory skin conditions and more recently, implicated in skin ageing. Therapeutic use of 'biotics' including prebiotics, probiotics, postbiotics, and synbiotics, which modulate the gut microbiota and production of microbially associated metabolites, influence the activity of the gut mucosal and immune systems and are showing promise as key candidates in addressing signs of skin ageing. In this review we aim to focus on the structure and function of the gut-skin axis and showcase the recent in-vitro and clinical evidence demonstrating the beneficial effects of select biotics in targeting signs of skin ageing and discuss the proposed mechanisms mediated via the gut-skin axis underpinning these effects.

RESUMO

BACKGROUND: Polypharmacy poses a growing concern in military and veteran populations due to complex health needs arising from service-related injuries and mental health conditions. This systematic review and meta-analysis aims to synthesize existing literature on polypharmacy prevalence, focusing on both general and psychotropic medications in military and veteran populations, and to identify contributing factors. METHODS: The study protocol adhered to PRISMA guidelines and was registered on PROSPERO. A comprehensive search across PubMed, Embase, Scopus, and Web of Science yielded 19 eligible studies. Two independent reviewers conducted study selection, data extraction, and quality assessment using standardized tools. The primary outcome was prevalence of polypharmacy and secondary outcomes included factors associated with increased polypharmacy risk. RESULTS: Pooled estimates revealed a high prevalence of psychotropic polypharmacy (36 %, 95 % CI: 23-49 %) and general polypharmacy (49 %, 95 % CI: -26-72 %) among active-duty military personnel and veterans. Heterogeneity was substantial (I2 = 100 %). Subgroup analyses in studies on psychotropic polypharmacy revealed that veterans with PTSD had a higher prevalence of polypharmacy (48 %) than those without PTSD (22 %). No significant differences were found in general and psychotropic polypharmacy prevalence based on medication threshold, mean age, and geographical location. Despite heterogeneity and bias, the study indicates generally high-quality research. CONCLUSION: The findings emphasize the critical importance of tailored medication management strategies for military and veteran personnel, considering mental health diagnosis like PTSD. Future research should prioritize longitudinal studies to discern long-term implications and develop targeted interventions for optimizing medication use in military and veteran populations.

RESUMO

Human breast milk (HBM) is the "gold standard" for infant nutrition. When breast milk is insufficient or unavailable, infant milk formula (IMF) can provide a safe and nutritious alternative. However, IMFs differ considerably from HBM in composition and health function. We compared the digestibility and potential health functions of IMF containing low cream (LC-) or high cream (HC-) with pooled HBM. After simulated infant digestion of these samples, the bioavailability of key nutrients and immunomodulatory activities were determined via cell-based in vitro assays. A Caenorhabditis elegans leaky gut model was established to investigate cream effects on gut health. Distinct differences were observed in peptide diversity and sequences released from HC-IMF compared with LC-IMF during simulated digestion (p < 0.05). Higher levels of free fatty acids were absorbed through 21-day differentiated Caco-2/HT-29MTX monolayers from HC-IMF, compared with LC-IMF and HBM (p < 0.05). Furthermore, the immune-modulating properties of HC-IMF appeared to be more similar to HBM than LC-IMF, as observed by comparable secretion of cytokines IL-10 and IL-1ß from THP-1 macrophages (p > 0.05). HC-IMF also supported intestinal recovery in C. elegans following distortion versus LC-IMF (p < 0.05). These observations suggest that cream as a lipid source in IMF may provide added nutritional and functional benefits more aligned with HBM.

RESUMO

Women's experiences of military service and transition occur within a highly dominant masculinized culture. The vast majority of research on military veterans reflects men's experiences and needs. Women veterans' experiences, and therefore their transition support needs, are largely invisible. This study sought to understand the role and impact of gender in the context of the dominant masculinized culture on women veterans' experiences of military service and transition to civilian life. In-depth qualitative interviews with 22 Australian women veterans elicited four themes: (1) Fitting in a managing identity with the military; (2) Gender-based challenges in conforming to a masculinized culture-proving worthiness, assimilation, and survival strategies within that culture; (3) Women are valued less than men-consequences for women veterans, including misogyny, sexual harassment and assault, and system failures to recognize women's specific health needs and role as mothers; and (4) Separation and transition: being invisible as a woman veteran in the civilian world. Gendered military experiences can have long-term negative impacts on women veterans' mental and physical health, relationships, and identity due to a pervasive masculinized culture in which they remain largely invisible. This can create significant gender-based barriers to services and support for women veterans during their service, and it can also impede their transition support needs.

RESUMO

When deciding whether to trust someone's claims, how do children combine-over multiple interactions-information about that person's general behavioral tendencies (traits) with that person's ongoing (and changing) rate of providing accurate claims? Children aged 4-8 played 11 rounds of a find-the-sticker game. For each round, an informant looked into two cups and made a claim about which cup held a sticker. Children guessed the sticker's location and the sticker's actual location was revealed. Prior to the game, children received information that the informant was either honest or dishonest. In Study 1 (N = 201, 105 female, 96 male), the informant provided inaccurate information on the first five trials and then provided accurate information for the remaining trials (55% overall accuracy). In Study 2 (N = 144, 89 female, 55 male), the informant produced a less predictable pattern of (in)accuracy, but remained 55% accurate overall. The trait information children initially received about the informant's honesty strongly influenced their epistemic trust when they lacked additional information about the informant's reliability (the earliest trials). When children's first-hand experiences with the informant prevented them from making strong predictions about the informant's future behavior, only children approximately 7 years and older utilized trait information to guide their epistemic trust. These results demonstrate some similarities in children's causal reasoning about the physical world and their social reasoning. The results also demonstrate developmental patterns in how children weigh different types of social information at different junctures in social interaction.

RESUMO

SCOPE: Osteopontin (OPN) is a multifunctional protein naturally present in mammals' milk, associated with immune homeostasis and intestinal maturation. This study aims to investigate the protein digestion pattern and the cellular bioactivity of bovine milk OPN digesta in vitro. METHODS AND RESULTS: A modified INFOGEST static in vitro infant digestion protocol and a Caco-2/HT-29 co-culture cell model are employed to evaluate the digestion properties and the anti-inflammatory effects of OPN. OPN is resistant to gastric hydrolysis but degraded into large peptides during intestinal digestion. Its 10 kDa digesta permeate with predicted extensive bioactivities protects the co-culture cell model from the inflammation-induced dysfunction by dose-dependently recovering the expression of occludin, claudin-3, and ZO-1. Low dosage of OPN significantly decreases the production of IL-8 and IL-6, and downregulates the mRNA and protein expression of MyD88, NF-κB p65, and IκB-α, whereas a high dose evokes a mild pro-inflammatory response. Interestingly, anti-inflammatory effect of OPN digesta is stronger than lactoferrin and whey protein concentrate counterparts. CONCLUSION: The findings demonstrate that the bioactive peptides released from in vitro infant gastrointestinal digestion of bovine milk OPN alleviates intestinal epithelial cell inflammation by inhibiting NF-κB pathway activation and potentiates the barrier function of the intestinal epithelium.

RESUMO

Young children, unlike adults, deny that improbable events can happen. We test two accounts explaining this developmental shift. The development = reflection account posits that this shift is driven by an emerging ability to reflect on modal intuitions. In contrast, the development = intuition account posits that this shift is driven by changes in modal intuitions themselves, due to age-related changes in what people know and how they sample their knowledge and memories. These accounts make competing predictions about how long children and adults should take to make possibility judgments. In Experiment 1, we asked 123 children (39 5-year-olds, 42 7-year-olds, 42 9-year-olds; 49.60% White) and 40 adults (50% White) to judge the possibility of 78 ordinary, improbable, and impossible events and recorded their response times. In Experiment 2, we tested an additional 52 adults (42.32% White) who were under speeded conditions and thus less able to reflect before responding. Our results favor the development = intuition account. At all ages, people judged improbable events more slowly than ordinary or impossible events, and slow responding did not consistently predict affirmation over denial. Further, adults' possibility judgments did not change under speeded conditions. We also fit a drift-diffusion model to our data, which suggested that adults and children may sample different kinds of knowledge when generating intuitions. Our findings suggest that possibility judgments are often driven by modal intuitions with little reflection, and that a developmental shift in what children know and how knowledge is retrieved can explain why these intuitions change over time.

RESUMO

A number of bacterial species are found in high abundance in the faeces of healthy breast-fed infants, an occurrence that is understood to be, at least in part, due to the ability of these bacteria to metabolize human milk oligosaccharides (HMOs). HMOs are the third most abundant component of human milk after lactose and lipids, and represent complex sugars which possess unique structural diversity and are resistant to infant gastrointestinal digestion. Thus, these sugars reach the infant distal intestine intact, thereby serving as a fermentable substrate for specific intestinal microbes, including Firmicutes, Proteobacteria, and especially infant-associated Bifidobacterium spp. which help to shape the infant gut microbiome. Bacteria utilising HMOs are equipped with genes associated with their degradation and a number of carbohydrate-active enzymes known as glycoside hydrolase enzymes have been identified in the infant gut, which supports this hypothesis. The resulting degraded HMOs can also be used as growth substrates for other infant gut bacteria present in a microbe-microbe interaction known as 'cross-feeding'. This review describes the current knowledge on HMO metabolism by particular infant gut-associated bacteria, many of which are currently used as commercial probiotics, including the distinct strategies employed by individual species for HMO utilisation.

RESUMO

The ability of gut commensals to adhere to the intestinal epithelium can play a key role in influencing the composition of the gut microbiota. Bifidobacteria are associated with a multitude of health benefits and are one of the most widely used probiotics for humans. Enhanced bifidobacterial adhesion may increase host-microbe, microbe-nutrient, and/or microbe-microbe interactions, thereby enabling consolidated health benefits to the host. The objective of this study was to determine the ability of human milk oligosaccharides (HMOs) to enhance bifidobacterial intestinal adhesion in vitro. This study assessed the colonisation-promoting effects of HMOs on four commercial infant-associated Bifidobacterium strains (two B. longum subsp. infantis strains, B. breve and B. bifidum). HT29-MTX cells were used as an in vitro intestinal model for bacterial adhesion. Short-term exposure of four commercial infant-associated Bifidobacterium strains to HMOs derived from breastmilk substantially increased the adherence (up to 47%) of these probiotic strains. Interestingly, when strains were incubated with HMOs as a four-strain combination, the number of viable bacteria adhering to intestinal cells increased by >90%. Proteomic analysis of this multi-strain bifidobacterial mixture revealed that the increased adherence resulting from exposure to HMOs was associated with notable increases in the abundance of sortase-dependent pili and glycosyl hydrolases matched to Bifidobacterium bifidum. This study suggests that HMOs may prime infant gut-associated Bifidobacterium for colonisation to intestinal epithelial cells by influencing the expression of various colonization factors.

RESUMO

OBJECTIVE: This scoping review will determine what causal theoretical frameworks have been used to examine veteran mental health help-seeking behavior. The review will also examine the causal factors proposed by these theoretical frameworks, and whether they account for the complex cultural, social, and affective experiences of veterans, which may drive both uptake or avoidance of mental health help-seeking. INTRODUCTION: Some military veterans delay mental health help-seeking, preventing early intervention, creating poor long-term quality of life and functional outcomes, and increasing the likelihood of reaching crisis point before seeking help. There is a distinct lack of research utilizing causal motivational frameworks to explain veteran mental health help-seeking behavior (both engagement and avoidance). To date, no review has been conducted on motivational frameworks used to explain veteran help-seeking behavior. This scoping review will be the first to identify the motivational models that have been used to explain veteran mental health help-seeking, as well as table the proposed causal factors, and determine whether the models account for the cultural, social, and affective experiences of veterans. INCLUSION CRITERIA: This scoping review will only consider studies on veteran cohorts. Studies in English that utilize or create an explanatory theory, model, or framework for veteran mental health help-seeking behavior will be included. Literature that focuses solely on intentions rather than behavior will be excluded. METHODS: Published and unpublished studies and gray literature will be included. Titles and abstracts will be screened, followed by full-text screening. Factors, theories, models, and frameworks used to explain veteran help-seeking behavior will be extracted, charted, and narratively summarized. The JBI methodology for scoping reviews will be used.

RESUMO

SCOPE: Human milk oligosaccharides (HMOs), multifunctional glycans naturally present in human milk, are known to contribute to the infant's microbiota and immune system development. However, the molecular specificity of HMOs on microbiota and associated fermentation is not yet fully understood, and is important for the development of infant formula optimum functionality. METHODS AND RESULTS: In vitro fermentation is carried out on structurally different HMOs with infant fecal inocula dominated by Bifidobacterium longum, Bifidobacterium breve, and Bacteroides. The gas, metabolite (SCFA, lactate, and succinate) profiles, and microbiota responses differ between individual microbiota inocula patterns regardless of HMO structure. In terms of HMO pairs with same sugar composition but different glycosidic bonds, gas and metabolite profiles are similar with the B. longum- and B. breve-dominated inocula. However, large individual variations are observed with the Bacteroides-dominated inocula. The microbial communities at the end of fermentation are closely related to the initial microbiota composition. CONCLUSION: The findings demonstrate that short-term in vitro fermentation outcomes largely depend on the initial gut microbiota composition more than the impact of HMO molecular specificity. These results advance the current understanding for the design of personalized infant nutritional solutions and therapies in future.

RESUMO

Humans often show variable responses to dietary, prebiotic, and probiotic interventions. Emerging evidence indicates that the gut microbiota is a key determinant for this population heterogeneity. Here, we provide an overview of some of the major computational and experimental tools being applied to critical questions of microbiota-mediated personalized nutrition and health. First, we discuss the latest advances in in silico modeling of the microbiota-nutrition-health axis, including the application of statistical, mechanistic, and hybrid artificial intelligence models. Second, we address high-throughput in vitro techniques for assessing interindividual heterogeneity, from ex vivo batch culturing of stool and continuous culturing in anaerobic bioreactors, to more sophisticated organ-on-a-chip models that integrate both host and microbial compartments. Third, we explore in vivo approaches for better understanding of personalized, microbiota-mediated responses to diet, prebiotics, and probiotics, from nonhuman animal models and human observational studies, to human feeding trials and crossover interventions. We highlight examples of existing, consumer-facing precision nutrition platforms that are currently leveraging the gut microbiota. Furthermore, we discuss how the integration of a broader set of the tools and techniques described in this piece can generate the data necessary to support a greater diversity of precision nutrition strategies. Finally, we present a vision of a precision nutrition and healthcare future, which leverages the gut microbiota to design effective, individual-specific interventions.

RESUMO

This study investigated the fermentation characteristics and microbial responses of human milk oligosaccharides (HMOs) by individual Bifidobacterium longum-dominant infant fecal microbiota. Fucosylated neutral HMOs (2'-fucosyllactose, 2'-FL; 3-fucosyllactose, 3-FL), sialylated HMOs (3'-sialyllactose, 3'-SL; 6'-sialyllactose, 6'-SL), and non-fucosylated neutral HMOs (Lacto-N-tetraose, LNT; Lacto-N-neotetraose, LNnT) were fermented in vitro, with fructooligosaccharides (FOS) and galactooligosaccharides (GOS) as positive controls. The fermentation rate was not affected by the molecular specificity of HMOs. Acetate (98-104 mM) and lactate (9-19 mM) were the primary metabolites at the end of fermentation. All six HMOs showed the same levels of acetate production, but sialylated HMOs produced significantly less lactate than neutral HMOs. HMOs and GOS could maintain the dominance or increase the relative abundance of Bifidobacterium longum, while FOS remarkably promote Klebsiella pneumoniae with the highest gas production and the least acetate and lactate yield. The findings are supportive to optimize infant nutrition strategies for enhanced functions.

RESUMO

Bifidobacteria are associated with a host of health benefits and are typically dominant in the gut microbiota of healthy, breast-fed infants. A key adaptation, facilitating the establishment of these species, is their ability to consume particular sugars, known as human milk oligosaccharides (HMO), which are abundantly found in breastmilk. In the current study, we aimed to characterise the co-operative metabolism of four commercial infant-derived bifidobacteria (Bifidobacterium bifidum R0071, Bifidobacterium breve M-16V, Bifidobacterium infantis R0033, and Bifidobacterium infantis M-63) when grown on HMO. Three different HMO substrates (2'-fucosyllactose alone and oligosaccharides isolated from human milk representing non-secretor and secretor status) were employed. The four-strain combination resulted in increased bifidobacterial numbers (> 21%) in comparison to single strain cultivation. The relative abundance of B. breve increased by > 30% during co-cultivation with the other strains despite demonstrating limited ability to assimilate HMO in mono-culture. HPLC analysis revealed strain-level variations in HMO consumption. Metabolomics confirmed the production of formate, acetate, 1,2-propanediol, and lactate with an overall increase in such metabolites during co-cultivation. These results support the concept of positive co-operation between multiple bifidobacterial strains during HMO utilisation which may result in higher cell numbers and a potentially healthier balance of metabolites.

RESUMO

A dosimetric study was undertaken to assess the ability of Cyberknife (CK), Volumetric Modulated Arc Therapy (VMAT), and TomoTherapy (Tomo) to generate treatment plans that mimic the dosimetry of high dose-rate brachytherapy (HDR BT) for prostate cancer. The project aimed to assess the potential of using stereotactic body radiotherapy (SBRT) for boost treatment of high-risk prostate cancer patients where HDR BT in combination with conformal external beam radiotherapy (EBRT) is the standard of care. The datasets of 6 prostate patients previously treated with HDR BT were collated. VMAT, CK, and TomoTherapy treatment plans were generated for each dataset using the target and organ-at-risk structures as defined by the Radiation Oncologist during the HDR BT treatment process. The HDR BT plan isodoses were also converted into planning structures to assist the other modalities to achieve a HDR BT-like dose distribution. CK plans were created using both the iris collimator (IC) and a multileaf collimator (MLC). Comparison of the techniques was made based on dose-volume indices. Each plan was created at centres experienced using the respective treatment planning systems (TPS). Planning target volume (PTV V100%), i.e., the volume of the planning target volume (PTV) receiving 100% of the relative dose, in VMAT and TomoTherapy SBRT plans was higher than HDR BT plans. PTV V150% and V200%, i.e., volume of the PTV receiving 150% and 200% of the relative dose, were approached on all the CK MLC and TomoTherapy SBRT plans. However, it is not presently achievable for "virtual brachytherapy" SBRT to replicate the same high intraprostatic doses as HDR BT while meeting the constraints on the organs-at-risk (OARs). Half of the CK IC plans achieved PTV V150% but this was at the expense of high rectal dose. TomoTherapy and CK MLC plans achieved PTV V150% and V200% but the bladder dose was higher compared to CK IC plans. VMAT exhibited excellent PTV coverage based on V100 and OAR sparing, but without any ability to achieve the high intra-prostatic doses of HDR (V150% and V200%). SBRT techniques can be used to deliver hypofractionated radiotherapy to the PTV V100%. Based on the comparison of "physical" dose distributions, SBRT cannot presently achieve the same high intraprostatic doses as HDR BT while respecting the OAR constraints. SBRT still remains an attractive treatment option for delivering hypofractionated treatments for prostate cancer compared to HDR BT, in particular as it is less invasive and less resource intensive. Long-term outcomes of clinical trials comparing HDR BT and SBRT "prostate boosts" may show whether the high intraprostatic doses are clinically significant and correlate with outcomes.

RESUMO

People with disabilities may behave in non-normative ways because they cannot act otherwise. This study explored whether U.S. children aged 3.00 to 8.99 years (N = 105) differ in their evaluations of people who commit norm violations when those persons have perceptual or physical disabilities. Across 12 scenarios, children were asked to explain different characters' non-normative behaviors and to evaluate each character's naughtiness. Characters were typically developing, had a physical disability, or had a hearing disability. Disabilities were described to participants but were not visually depicted. Across moral and conventional norm violations, children aged 4.5 years and older judged characters with disabilities as less naughty than characters without disabilities, whereas younger children (3 and 4 years) judged all characters as equally naughty. Children's explanations for characters' non-normative behaviors (acknowledging characters' physical/auditory limitations and inferring negative attributes) significantly predicted their naughtiness judgments; this was true for participants across the sampled age range. Thus, preschool children demonstrated flexibility in their moral judgments across a variety of everyday behavioral violations, tempering their negative evaluations of persons who committed non-normative behaviors when those persons had unseen disabilities that could reasonably account for their actions. Parents and teachers may be able to build on these early moral intuitions to foster greater acceptance of persons with disabilities.

RESUMO

Factors affecting milk and milk fraction composition, such as cream, are poorly understood, with most research and human health application associated with cow cream. In this study, proteomic and lipidomic analyses were performed on cow, goat, sheep and Bubalus bubalis (from now on referred to as buffalo), bulk milk cream samples. Confocal laser scanning microscopy was used to determine the composition, including protein, lipid and their glycoconjugates, and the structure of the milk fat globules. BLAST2GO was used to annotate functional indicators of cream protein. Functional annotation of protein highlighted a broad level of similarity between species. However, investigation of specific biological process terms revealed distinct differences in antigen processing and presentation, activation, and production of molecular mediators of the immune response. Lipid analyses revealed that saturated fatty acids were lowest in sheep cream and similar in the cream of the other species. Palmitic acid was highest in cow and lowest in sheep cream. Cow and sheep milk fat globules were associated with thick patches of protein on the surface, while buffalo and goat milk fat globules were associated with larger areas of aggregated protein and significant surface adsorbed protein, respectively. This study highlights the differences between cow, goat, sheep, and buffalo milk cream, which can be used to support their potential application in functional foods such as infant milk formula.

RESUMO

BACKGROUND/OBJECTIVES: This study aimed to establish a mother and child cohort in the Chinese population, and investigate human breastmilk (HBM) composition and its relationship with maternal body mass index (BMI) and infant growth during the first 3 mon of life. SUBJECTS/METHODS: A total of 101 Chinese mother and infant pairs were included in this prospective cohort. Alterations in the milk macronutrients of Chinese mothers at 1 mon (T1), 2 mon (T2), and 3 mon (T3) lactation were analyzed. HBM fatty acid (FA) profiles were measured by gas chromatography (GC), and HBM proteomic profiling was achieved by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS). RESULTS: During the first 3 mon of lactation (P < 0.05), significant decreases were determined in the levels of total energy, fat, protein, and osteopontin (OPN), as well as ratios of long-chain saturated FA (including C16:0, C22:0 and C24:0), monounsaturated FA (including C16:1), and n-6 poly unsaturated FA (PUFA) (including C20:3n-6 and C20:4n-6, and n-6/n-3). Conversely, butyrate, C6:0 and n-3 PUFA C18:3n-3 (α-linolenic acid, ALA) were significantly increased during the first 3 mon (P < 0.05). HBM proteomic analyses distinguished compositional protein differences over time (P = 0.001). Personalized mother-infant analyses demonstrated that HBM from high BMI mothers presented increased total energy, fat, protein and OPN, and increased content of n-6 PUFA (including C18:3n-6, C20:3n-6 and n-6/n-3 ratio) as compared with low BMI mothers (P < 0.05). Furthermore, BMI of the mothers positively correlated with the head circumference (HC) of infants as well as the specific n-6 PUFA C20:3n-6 over the 3 time points examined. Infant HC was negatively associated with C18:0. CONCLUSION: This study provides additional evidence to the Chinese HBM database, and further knowledge of FA function. It also helps to establish future maternal strategies that support the healthy growth and development of Chinese infants.

RESUMO

Societies are rife with out-group discrimination and mistreatment. One way that children might acquire social biases that lead to such outcomes is by overhearing derogatory or disparaging comments about social groups. Children (n = 121) overheard a video call between a researcher and an adult or child caller who made negative claims (or no claims) about a novel social group. Immediately and following a 2-week delay, older children (7-9 years) who overheard the message demonstrated stronger negative attitudes toward the group than children who heard no message. Younger children's (4- to 5-year-olds') attitudes were generally unaffected by these claims. Thus, overhearing brief, indirect messages from children or adults had robust and lasting effects on the social biases of children 7 years and older.

RESUMO

OBJECTIVE: To describe key practical knowledge and skill components required for clinicians involved with the assessment of military personnel and veterans. CONCLUSIONS: Assessment of military and veterans' mental health issues involves a tailored history-taking process that includes specific aspects of service, transition and reporting requirements. Recommendations for the detailed assessment of military personnel and veterans are provided. Comorbid conditions, chronic pain and the needs of both women and older veterans are also discussed.
